To @ZZ whom it may concern,.- serve simply as an exhaust, leading eitherto Be it known that I, WILLIAM E. GOOD, of the air or a condenser. thecity and county of Philadelphia and State H indicates the valve-stem ofthe highof Pennsylvania, have inventeda certain new pressure engine, andI the valve-stem of the 5 and useful Improvement in Steam-Engines,low-pressure engine, a connecting-rod J lead- 55 of which the followingis a true and exact deing from stem H to link-motion L N in the onescription, reference being had to the accomcase and a similarconnecting-rod K leading panying drawings, which form a part of this toa link-motion M O in the other case.

Thus itwill be Ioo seen that by the paradoxical means of shortening theadmission to the low-pressure cylinder as its work increases I secure anincreased supply of steam for it and at a higher pressure. It is ofcourse obvious that a decrease of work in the low-pressure cylinderwill, acting through its inverted governor, diminish the back-pressurein the high-pressure engine, and by thus diminishing the work to beperformed by that engine will effect a shortening of admission of highpressure steam to it. y

Referring now to a special use of my device, I would state that Y and Yindicate the blowing-cylinders of the high and low pressureblowing-engines. As shown in Figs. 4t and 5, there are six pairs ofblowing-engines, each having one high-pressure engine and one 10W-pressure engine and six points of use (indicated at Z Z Z) and which maybe blast-furnaces, converters, or any other device where air is used.Each pair of blowing-engines connects with a single point of use Z-as,for instance, through the air-conduits y y-unitin' in a single conduit Yor assed inde` pendently, if desired, to the point of use. The receiverF in the plan shown is made continuous by extensions F F2 F3 F4 F5, andvalves f f 2 f3 f4, & c., are arranged in it, as shown.

In the diagram of my plant I have marked each pair of engines with anumeral from one to six. Normally, I will suppose that the valves f f3 f5 f 7 f f11 are open and the others closed. This Will connect each pairof high and low pressure engines, as indicated at Fig.

' 1. If nowone of the engines breaks down, or it isdesired for otherreasons to throw it out of use, taking, for instance, the high-pressurecylinder-engine of the first set, itis necessary only tovclose the valvef', when the low-pressure engine of'the set can be run independently ofthe high-pressureengine. The plan would then be as before, except thatlive steam would be admitted to the low-pressure engine independently,or by opening the valve f2 the exhaust from the high-pressure engine inthe second set would pass both to it and to its own proper engine in thelow-pressure set, the admission of the high-pressure engi-ne beingincreased to the extent which would enable it to supply steam to the twolow-pressure engines. The other combinations are obvious and need not bespecifically pointed out.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In combination with high and low pressure cylinders connected by aconduit or receiver, a governor regulating the admission of steam to thehigh-pressure cylinder, said governor being arranged to lengthen theadmission as the work on said cylinder increases, and a governorregulating the admission of steam to the low-pressure cylinder, saidgovernor being arranged to shorten the admission as the Work on thatcylinder increases, substantially as and for the purpose specied.

2. The combination of two steam-engines disconnected as to theirreciprocating or rotative movements, a receiver connecting the exhaustof one engine-cylinder with the admission of the second, a governorregulating the admission of steam to the high-pressure cylinder andVarranged to increase the admission as the work on said cylinderincreases, and a governor regulating the admission of steamto thelow-pressure cylinder, arranged to shortenthe admission as the work onsaid cylinder increases, substantially asand for the purpose specified.
